Carrier-grade Wi-Fi, DAS, ERRCS, and CBRS / private LTE — engineered for federal commands, transit tunnels, healthcare environments, and the rooftop and OSP spaces in between.
Wireless is how everything else moves — the laptops on the operations floor, the carts in the warehouse, the public safety radio in the stairwell, and the cellular signal that disappears the moment a passenger walks into a tunnel. Walker Telecomm designs and installs in-building wireless for federal commands, transit agencies, hospitals, gaming floors, and large education campuses where coverage and capacity are decided in the design phase, not after move-in.
Every deployment starts with predictive heatmap and ends with a post-install validation walk. We coordinate with carriers, AHJs, and IT — and we sequence installation around live traffic, off-hours, and the people who can't have the network down.
A simulated floor with four access points and a roaming client. Each AP's coverage radiates and overlaps; the client roams the corridor and hands off between APs — the kind of plan we model with Ekahau before a single cable gets pulled.
Radiating coax, fiber, distributed antenna systems, and complete wireless infrastructure inside the SFMTA municipal tunnels — supporting a neutral-host environment for every major cellular carrier. Installed on rail trucks, in off-hours, without disrupting service to 48,000 daily passengers.
